It does not. It describes "informal logic" which is a philosophical term.

We're not having a philosophical discussion. We're having a mathematical one.

"Symbolic logic."

    I hope you don't insist that your kid learn symbolic logic unless he's really fascinated by it.

No for every fucking reason in my original post. The fact that you think "symbolic logic" and "informal logic" are the same thing is a strong indicator that not only do you need to focus on your rhetoric, you need to retake algebra.

Well, the reason you

is because you don't know what you're talking about.

Here's symbolic logic:

[(p ⊃ q) ∧ (q ⊃ r)] ⊃ (p ⊃ r).

And here's algebra:

(x² + y²)² = (x² - y²)² + (2xy)²

They are only vaguely related. You can't reasonably expect anyone to learn about one from being taught the other. And both are of limited utility if what you want is to learn to reason.
